作者提出了一种基于双耳刺激时间差的声源定位理论。该假说依赖于已知的小神经纤维的传导速度慢和空间总和现象。它假设听道的一些次级纤维分裂，发出同侧和对侧的分支。还有一个进一步的假设，即这些神经元与每一侧的其他纤维形成突触连接，后者与对侧和同侧神经元都形成突触。然后，如果声音在正中平面，则在每一侧的三级纤维的中心组中，总和效应将是最大的。如果声源移动，叠加效应将导致通过第三区突触的传输移动。这提供了作为双耳刺激的时间变化的结果的神经放电模式的空间变化。这种中心的解剖位置建议在下丘或内侧膝状体。提出了可能的实验步骤。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The author presents a place theory of sound localization based upon the time difference of stimulation of the 2 ears. The hypothesis depends upon the known slow rate of conduction in small nerve fibers and the phenomenon of spatial summation. It assumes that some secondary fibers of the auditory tract divide, sending branches homolaterally and contralaterally. There is a further assumption that these neurons make synaptic connection with other fibers on each side, the latter neurones synapsing with both contralateral and homolateral neurones. Then, if the sound is in a median plane, the summation effect would be maximal in a central group of the tertiary fibers on each side. If the sound source is shifted, the summation effect would result in a shifting of the transmission through synapses in the tertiary zone. This provides a spatial change in the pattern of nerve discharge as a consequence of a temporal change in the binaural stimulation. The anatomical location of such a center is suggested either in the inferior colliculus or the medial geniculate body. Possible experimental procedures are suggested.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
